The Master Lock excell laminated padlocks features a wide laminated steel body for maximum strength and reliability, and are surrounded by stainless steel and zinc outer components for weather resistance. The Rust-Oleum certified protection protects against rusting on the lock body; and covered clock body, keyway, and shackle seals offer additional weather protection: protects against snow, Rain, dirt, Mud, grime and salt. The 8mm diameter octagonal shackle is 38mm long and made of tough-cut boron-carbide, 50% harder than hardened steel, offering maximum resistance to cutting and sawing. The 4-pin cylinder prevents picking and the Dual locking ball bearings provide maximum resistance against prying and hammering. Master Lock is recognized around the world as the authentic, enduring name in padlocks and security products. In 1921, Harry Soref invented the first laminated padlock. And since our founding in 1921, we have worked hard to earn and maintain the trust of our customers by delivering on our promise of strength and quality and by continually setting new standards for lock design, application and performance. As the largest global manufacturer and marketer of padlocks, we continue to build our founder’s passion for innovation, quality, and compelling value into our expanding lines of security solutions.
